HAT SWEAT SEWING TTACHMENT Filed April 21, 1949 2 sheets-Sheet 2 Patented Mar. 20, 1951 UNITED Yswan-:s PATENT as- 46,125 K Y Y 'oriliia is. Reid, Keilworth, N. J., aspsigmm` to The Singer Manufacturing Company, Elisabeth, N. Ji, a corporationof New Jersey Appli-tation Apr'ii 21, 1949', serial o. 'stati eclaims. kv(o1. liz- 136) This invention relates to attachments for sewing machines and more particularly to an attachment for Vguiding the component elements of a waterproof hat sweat to the stitch forming mechanism of sewing 'machines having an'interrupted feed and a laterally vibrating' needle, such', for example, as the ISii'iei N0. 107W9 machine which produces, in each cycle, one straightawa'y stitch and two transverse stitches. y

The invention has as its primary object to provide van attachmentwhich will so present to the lstitch-forming mechanism of a machine of this nature, a leather sweatband and a previously united reed, reed-cover-s'trip and a protector strip of waterproof material, that one of the two flaps of thereed-cover-strp will ybefunited to one marginal portion of the sweatba'nd without the possibility of the needle puncturing the waterproof strip or the usual bead which encloses the reed.

The previously united reed, reed-cover-strip and the strip of waterproof material, which this attachment is designed to handle, is the product of the electronic seaming machine which forms the subject of the pending United States ,patent application ofO. B. Reid', Serial No. 55,513, led October 20, 1948;

Another object of the invention is to provide', in an attachment of this nature,` improved means for guiding one edge of the leather sweatband substantially into contact with the base of the bead, comprising the usual reed and its covering strip, and means for deecting the bead proper to one side and holding it out of the path of 're-i ciprocation of the needle to prevent the needle from contacting the bead. y

Another object is to provide, in an attachment as above described, a 'guide for the leather sweatband which willaccurately hold one edge of the sweatba-nd relative tothe needle s'o that when the needle is reciprocated in one of its two lateral positions, in which it makes its depth stitch, it will penetrate the sweatband 'and one flap of the reed-cover-'strip and whenu reciprocate-d in its other lateral position', in which it makes its edge stitch, it will just miss the edge of the sweatband and will penetrate only the flap of the reed-cover'- strip.

Still another objectv is to provide an attachment of this nature iri which the Sweatband guide -iS automatically adjustable and is capable of adapting itself to varying widths and curvatures of sweatbands.

With the labove and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations 'and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodi; ment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Referring more specifically to the drawings, this invention is' disclosed as embodied in an ati tachment comprising a base-plate B adapted to' be adjustably secured upon the cloth-'plate C of a sewing machine by screws I passing through a slot 2 in the base-plate and threaded into the cloth-plate. The sewing machine to which the present attachment is particularly adapted also includes va vertically reciprocating and laterally vibrating needle-bar 3 carrying, at its lower end, an eye-'pointed thread-carrying needle l which is designed to cooperate with a conventibhal lower loop-taker mechanism, not shown, in the formation of edge and depth stitches. Fitted into the cloth-plate,` in the region of lthe stitch foriningr mechanism, is a throat-plate T having slots 5 (Fig. 6) through which operates a feed-dog for-ming a part of a work-feeding mechanism, not shown. This feedingl mechanism is adapted so to advance the work through the machine that after each forward feed of the work4 and the making of an edge stitc'hthe work is held stationary while the needle-bar and the needle carried thereby are' moi/ed laterally to the left and reciprocated to forni a rist offset, or depth stitchin the work perpendicular to the line of feed and then moved laterally to the right and again reciprocated to form a second offset stitch parallel to the rst oiset stitch. This makes a well known form of seam which is commonly used in attaching s-weatbands to reed-cover-strips.

The work which this attachment is designed to handle comprises a leather sweatband S, a reed-cover-strip P, having a central hollow beadv portion b, enclosing a reed R, and oppositely disposed laps f1 and f2, and a strip of waterproof material M having one edge portion bonded between the flaps f1 and f2 of the strip P, as shown in the above mentioned United States patent-application of O. B. Reid.

The work is held down upon the throat-plate T and in position to be engaged by the feeding mechanism by a presser-foot 6 carried lby a spring-depressed presser-bar '1.

As shown most clearly in Figs. 2 and 6, the presser-foot is formed with a transverse slot 8 for the passage of the reciprocatory and vibratory needle 4 and, in its under side, with a longitudinal groove 9 (Fig. 6) for the passage of the bead b of the strip P.

Movably mounted on vertically disposed Studs I Il and II, secured to and extending upwardly from the attachment base-plate B, is a presserplate I2 on the under side of which are adjustably mounted, as by screws I3 and I4 passing through slots i5 and I6, a pair of spaced guide blocks Il and I8, (see Figs. 5 and 5a). The adjacent ends of these guide blocks are beveled upwardly and outwardly, as indicated at IIBv and I8a. Above the space between the ends of the guide blocks the under side of the presser-plate I2 is formed with a downwardly open channel I9. Thus the wall of the channel I9 and the proximate ends of the guide blocks I'I and I8 afford a bellmouthed upwardly flaring guideway for the bead band the adjacent neck portion n of the reedcover-strip P, while the blocks I'I and I8 bear downwardly upon the aps f1 and f2 to smooth and slightly tension the reed-cover-strip.

Beehive springs 20 surrounding the studs IIJ and AII between the presser-plate I2 and pressure-adjusting nutsV 2|, threaded on the studs, exert a yielding downward pressure on the plate I2 andA blocks Il and I8. By adjusting the nuts the pressure on the flaps f1 and f2 may be Varied.

The leather sweatband S passes through a guide H comprising a supporting shank 22 pivotally mounted on a threaded upright stud 23 carried, by the base plate B. The shank is formed with an aperture 24 which receives the head of a locating pin 25 carried by the base plate B to hold the shank and the parts carried thereby in loperative position. A beehive springl 26 surrounding the' stud 23, between the shank 22 and a nut 2'I threaded on the stud, normally serves to hold the'shank depressed to maintain the pin 25 in the aperture 24 but permits raising of the shank to clear it of the pin 25 after which the shank and the parts carried thereby may be turned about the axis of the stud 23, as indicated in dotted lines in Fig. 2, to remove the sweatband guide H from operative position. The shank 22 has a raised portion 22al upon which is adjustably secured, by screws 28, the foot portion 29a of a normally Viixed edge guide 29 comprising the overturned edge portion 29b of a sweatband supporting plate 30. The guide 29 engages one edge of the leather hat sweat S and so posi-v tions it that, in the lateral position of the needle j in which it makes an edge stitch, the needle just barely misses the edge of the hat sweat and *"Atthe upper side of the sweatband guide the overturned portion 3|a slides beneath the free endportion of a guide plate 32 secured, at one end, as by soldering, to the portion 29b of the fixed edge guide.

The plate 3I and the edge guide 3|a carried thereby are normally urged toward the edge guide 29b by a spring 33 having its opposite ends connected to ears 34 and 35 secured to and depending, respectively, froin the plates 30 and 3|. This insures that the right hand'edge of the sweatband S will be held in contact with the edge guide portion 29b and thereby properly aligned relatively to the path of reciprocation of the needle., A stop block 36 secured to the under side of the plate 30 limits the movement of the plate 3| under the iniluence of the spring 33. The plate 3l and the edge guiding portion 3|a carried thereby are free to be moved to the left, in opposition to the spring 33, to accommodate sweatbands of various widths and curvatures.

As hereinbefore stated it is desirable, in making the stitches along the right hand edge of the leather hat sweat and through the ilap f1 only, that the needle penetrate the ilap closely adjacent the bead b Without contacting the bead and without penetrating the strip of waterproof material M. This is eiected by deflecting the bead out of the path of the needle immediately in advance of and adjacent the needle. The means for accomplishing this includes a guide blade 3l (Figs. 2 and 4) secured upon the under side of a plate 38 adjustably secured by screws 39 to the base plate B. The forward free edge of the blade 3l overlies the flap f2 and engages theneck n below the bead b, at that side of the bead remote from the needle, as seen most clearly in Fig.' 4. Cooperating with the guide blade 3l is a delector plate 40 adjustably secured upon the upper side of the plate 38 by screws 4I. The outer free end of this plate is turned downwardly as at i2 (Fig. 4) and engages the bead b at the side thereof adjacent the needle. The plate t is so adjusted on the plate 38 and relative to the blade 3l that the bead b, the neck n and the edge of the sheet M within the neck are deflected and held out of the path of reciprocation of the needle so that the needle in its descent will just miss the bead and the sheet M.

As shown in Figs. v2, 4 and 7, the side wall 29b of the fixed edge guide 29 is cut away at its delivery end as indicated at 29C. This aords sufcient clearance to permit the sweatband to contact the downturned end 42 of the bead defiector plate 40 even when the sweatband is of slightly curved form. v

From the foregoing it will be apparent that this invention has provided a hat sweat sewing attachment which will guide reed-cover strips and sweatbands of various widths and curvatures to the stitch forming mechanism of a sewing machine so that the reciprocating and laterally vibrating needle will make depth stitches through one edge portion of the sweatband and through one flap of the reed-cover-strip and edge stitches V. through the flap only, closely adjacent the edge of the sweatband. Likewise, ity will be apparent that themeans provided, for deflecting the bead and its neck away from the needle will insure against penetration' of the bead` and the waterproof material M' by the needle.

Having thus set forth the nature of the invention, what I claim herein is:
